JOSEPH M. POWELL, 0F BROOKLYN, ENDEANA.

sHALE ruinas .AND nxcnvntroia.

Brooklyn, in the county of vMorgan and` State of Indiana, have inventeda new andv useful Shale Planer andl Excavator, of which the following isa specification.

ln the manufacture of brick, drain tile, etc., natural deposits of clay,shale,'etc., are used as a basis for" the plastic. Such natural from topto bottom so that it is often desirable, and in .manyy cases absolutelyessential for economical use, to mix the materials comingl from diere'ntportions of the de. posit. Heretcfore such deposits have been worked outin comparativelyfshallow depths either by hand mining or by the use ofsteam shovels, etc., and much labor has been required in yproducing`proper mixtures of the material. y

rEhe object of my present invention hase been to produce an apparatuscapable of cutting the entire vertical face of a clay or shale bankunder such conditions that a thorough and substantially yuniform mixtureof the deposit may be automatically produced, the apparatus in operationtaking the place of a very considerable number of laborers.

The accompanying drawings illustrate my invention. l

Figure 1 is a sideelevation of the apparatus in operative position; Fig.2 an enlarged plan in partial horizontal section; Fig. 3 a fragmentaryvertical' section on the line 3-3 of Fig. 2; Fig. 4 a fragmentary detailof the cutter chain; Fig. 5 a section on l detail of one side lof theputter chain and its adjacent g'uideway; and Fig. 7 a fragmentaryydetail of avrnoditied wearing shoe for theI cutter chain. In thedrawings, 10 indicates .a track which is laid upon the ground at thebottom of the bank 11 and parallel with its verti.- cal face. Mountedupon the track 10 aretlie wheels 12 of a carriage 13 and mounted uponthe carriage 13 is a main frame; or

14'which is slidably mounted upon framel 13 transversely of the track10.

` Specification of Letters Patent. v Application filed August 5, 1912.Serial-No. 713,243. l

` upon the carriage notches 27 formed in the bit. embodies a tube orpipe 28 adapted to rc-' cent' cross pin 30.

The transverse adjustment of the tower 14v Patent-ed Jan. 6, 1914.

13 is obtained by means of a temper-screw crank 16.

Arranged at the lower inner corner of the tower 14 is a pair ofl idlersprockets 17 and vertically above these sprockets, at the upper end ofthe tower, is a pair of idler sprockets 18. Mounted in suitable bearingsat the lower end of the tower14 is a shaft 19 which carries a pair ofdriving sprockets 21 which are arranged in the 'vertical planes of thesprockets 17 and 18,

Any one of a number'of kinds of cutters may 15 provided with a hand' nand over the three sets of sprockets is passed the cutter chain 22.v

be attached to cutter chain 22,` dependingvl upon the particularcharacter of the deposit which is to be mined; but for ordinary clay orshale deposit l lind it advisable to use comparatively narrow cutterbits 23 each of whichY may be mounted in a holder 24 having aytransverse opening 25 for the recep` tion of the' bit, said bit beingheld in any one of its possible positions by means of a f Holder 24cross pin 26 taking linto one or the other of ceive a cross pin 29connecting the pair of link belts forming the chain 22. Holder 24 atrear end is. provided with a notch or seat 30 which is adapted toreceive the adja- Both preceding and following each cutter 23 I arrangea scraper 31 the purpose of which will appear.

The vertical face of the tower 14 is prc videdywith two vertical guides32 for the recept-ion and support of the active portions of. chain 22,and said chain is provided at suitable points with wearing members tocooperate with the guides, such wearing members being anti-frictionrollers 33, as shown in Fig. 4, or sliding shoes A34, as shown in Fig.

y7. Shaft 19 carries gears 41, 41 at its .opposite ends, and these gearsmesh with gears 42, 42 carried byshaft 43. Shaft 43 carries gear 44which meshes with gear 45 carried by shaft 46 which also carries a beltpulley 47 connected by belt 48 with a .clutch pulley 49 carried by shaft50. Shaft 50 carries pulley 51 which is connected by a belt 52withpulley 53 carried by the main shaft of motor 54. It is off course tobe understood that the particular train of gearingand belting is merelytypical, as indicating some suitable driving connection between themotive power and the cutter chain by means of which it may be driven ata speed suitable to the material being operated upon.

The shaft 43 carries a friction dlsk 55 which coperates with\ andjustable friction disk splined upon a shaft 57 connected by gears 58and 59 with -a shaft 60 upon which is splined asprocket wheel 61connected by a sprocket chain 62 toa countershaft 63. Countershaft 63carries a pair of sprocket wheels from which run two chains 64, 64 inopposite directions to sprockets 65, 65 carried by axles 66, 66 to whichthe traction wheels 12 of the carriage 13 are secured, the arrangementbeing such that the traction wheels 12 may be driven at any desiredspeed in either `direction so as to transport the entire a Aparatushorizontally parallel with the working face of the bank 11. The frictiondisk 56 may be adjusted relative to disk 55 by an ordinary adjustinglever 71 the details of which are too well knownto re* quiredescription. Similarly, the d1sk 56 may be-moved into or out ofoperative engagement with disk y55 by an ordinary and well knownoperating. lever 72.

The active portion ofthe cutter chain, between the wheels y17 and .181sarranged within a verticall placed, U-shaped trough or chute,l 73 whicat its lower end, is provided lwith an upwardly inclined bottom trough74 which is arranged arallel with that portion of the cutter cham whichextends between the wheels'17 and 21. Arran ed above the trough 74 is adownwardly inclined plate 75 upon which the larger proportion of themined material will fall and from which it will slide onto the receivingend of an endless delivery belt 76 which is extended from the outboardedge' of the tower 14 in such position that a tram car 77 may be placedbeneath the delivery end of the belt. This tram car traverses a track 78which is held parallel with track 10 and thecar is drawn along with theapparatus by means of a chain or other suitable detachable connection79. Shaft 43 carries a sprocket wheel 81 which is connectedy by chain 82with a sprocket wheel 83 carried by a shaft 84 which carries one of therollers 85 upon which the endless belt 76 is mounted.

Adjacent the outside of each sprocket Wheel 17 I arrange a verticallyadjustable shoe 86 which is 'carried at the lower ends by a pair of rods87 connected by a rod 88 with a controlling lever 89 (see dotted lineslin Fig. 1) the arrangement being such that these shoes may beindependently raised and lowered.

When the motor 54 is an electric motor, I provide a suitable feed wirewhich passes which contacts with a wire which may bel arranged along thetop of t-he bank. It is convenient, wlth such an arrangement, to providethe feed wire with suilicient slack to permit the placing of a weightedpulley block 94 in the bight of the slack.

The operation is as follows :Tracks 10 and 78 being held adjacent thebank 11 4in the manner indicated in Fig. l, the tower is adjustedtransversely ofthe carriage 13 until the cutters 23'project a suiiicientdis-l i tance into the vertical face of thebank 11, whereupon theapparatus isputy in motion and the cutters move downwardly across theface of the bank 11 and at the s e time the carriage 13 is advancedslowly a on the track 10.I Comparatively narrow an shavings of mud orshale are thus cut, from the face of the bank and, as several cuttersare simultaneously in operation at different heights ofthe bank, it willbe apparent that the cuttings will fall in a substantiall uni formmixture upon platform 75 and e de livered by carrier 76 to' the car 77.The intv terial which gets below the platform 75 is carried by theScrapers 31 up the trough and delivered tov the carrier 76. During theadthin 1 vance of the apparatus ,along` track'lO that shoe 86 which isadvanced will be raised while the rearward shoe 86 will be in its lowestpossible position thus carrying along the cuttings which may have fallenthat low so that the will be gathered up by the Scrapers and de iveredto the carrier.

I prefer to make the cutters, 23 comparatively narrow because it isquite common to findv stones embedded in the clay or Shaka.

and if the cutters are narrow no difficulty is experienced in breakingup such harder material. l

After the entire apparatus has traversed a sufficient length of the bankthe wheel 56 is shifted to the opposite side of the center of wheel andthe operation is repeated with the carriage 13 moving in the oppositedirection. From time to time, as the need arises, the tower is movedtransversely of the carriage 13 toward the face of the bank. l
